Cleaning the inside of DOT headlights

[frank j. bauer]

i'm not talking about ambient humidity.
when you replace your bulbs you don't typically coat the interior of 
your headlight assembly with H2O in its liquid state.
getting the interior of the headlight assemblies dry at room temperature 
may take a long time, especially in high humidity, and therefore that 
option depends on your schedule.
your experience may vary...
